Why you can't test straight away

Pregnancy tests detect hCG, a hormone that only starts to be made after the embryo implants, usually 6 to 12 days after ovulation. Levels then roughly double every couple of days, so testing too early can give a negative result even if you are pregnant.

If the test is negative

If your period still hasn't arrived, test again in two to three days. If you keep getting negatives and your period is more than a week late, a doctor can check for other causes.

A 32-day cycle sits within the typical adult range of 21 to 35 days.
